SOLOMON M. KEMP, OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE-HALF TO WILLIAMT. HENDERSON, OF SAME PLACE.

GAS-BURNER.

fPEC-IFICATION forming part of Letters Patent No. 513,790, dated January80,1894. Application filed January 31, 1893. Serial No- 460,265. (Nomodel.)

To all whom it may concern.-

Be it known that I, SOLOMON M. KEMP, a c tizen of the United States,residing at Baltimore city, in the State of Maryland, have inventedcertain new and useful Improvements in Gas-Burners, of which thefollowing is a specification.

This invention relates to an improvement in gas-burners, and relatesespecially to that class of burners, wherein the object sought to beaccomplished, is'thc generation of heat bythe combustion of gas.

\Vith this object in view, the invention consists of a novelconstruction of the feeding and distributing devices, which I shallpresently point out.

In the accompanying drawings,Figure 1 is a vertical section of theburner showing my nduction and distributing devices; Fig. 2 an lnvertedview of the annular chamber, E;

-Fig. 3 a top view of the distributing cham-' ber, O.

Referring to the accompanying drawings, the letter, A, represents thecasing, which contains and supports the burner.

The letter, B, represents the feed pipe through which the gas is led tothe distribut- 1ng chamber,,0, from which pipes, D, preferably three innumber lead the gas to the annular chamber, E, having jet apertures, e,therein. The gas is ignited at this point.

The letter, F, designates a cylinder having perforations,f, therein andmounted on the annular chamber, E.

The letter, G, represents a flame-spreader mounted on the cylinder. Theannular chamber, the cylinder and the flame-spreader, are drawn closelytogether by a bolt, g, passing through the metal piece, g, in form likethe inverted frustum of a cone. One end of the bolt is secured to thespreader, G. The other is screw threaded and passes through the hole, 9in the hub, 2', to which the supporting arms, '6, preferably formedintegral with annular chamber, E, are attached. A nut h, engaging thescrew-threaded end of the bolt, 9', serves to draw the parts closetogether. The cone-shaped piece, g, serves to relieve the thinperforated cylinder, F, when the nut, h, is screwed up. The imperforatecylindrical band, I, surrounds the distributing pipes,

D, and extends from the top of the casing, A, to the annular chamber, E.A bulged collar, d, surrounds the band, I, and has two series ofperforations, cl, and (1 intermediate of which is secured thespring-fingers, k, for holding the chimney in position.

.My burner is of the Argand type, having an inner draft from the holes,A, in the easing, A, through the imperforate band, I, and

out through the perforations, f, in the cylinder, F; and an outer draftfrom the perforations, d, in the collar d, below the bottom edge of thechimney, L, and out through the perforations, d inside the chimney butoutside the line of flame issuing from the jetapertures, e. The doubledraft supplies oxygen freely to the flame and on both sides thereof,thus effecting a more perfect combustion of the carbon in the gas,whereby more heat is generated and the burner is more nearly smokeless.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination in a gas burner, of a feed pipeleading to a distributing chamber; distributing pipes leading from saiddistributing chamber to an annular chamber having jet-apertures thereinacentral hub having radial arms secured at their extremities to theannularchamber; a perforated cylinder mounted on the annular chamber; aflamespreader mounted on the cylinder; 'means connecting theflame-spreader with the hub to hold the fiamespreader and said hub inposition on the annular chamber; a bulged, perforated collar surroundingthe distributing pipes, and fingers secured to said collar forsupporting the chimney; substantially as described.

. 2. The combination in a gas burner, of a feedpipe, connecting with adistributing chamber; distributing pipes leading from said distributingchamber to an annular chamber having jet-apertures therein; a perforatedcylinder mounted on said annular chamber; a flame-spreader mounted onthe cylinder; a band surrrounding the distributing pipes, and a bulgedcollar surrounding said band and having an upper and a lower series ofperforations, and spring fingers mounted on said collar, between the twosaid series of perforations, for securing the chimneyin position;substantially as described. i

3. In a gas-burner the combination of a feed pipe connecting with adistributing chamber; an annular chamber having jetapertures therein;distributing pipes leading from the distributing chamber to said annularchamber; a central hub having radial arms secured at their extremitiesto the annular chamber; a perforate cylinder mounted on the said annularchamber; a flamespreader mounted on the cylinder; an inverted frnstum ofa cone interposed between the central hub and the flame-spreader; abolt, g, passed longitudinally through the inverted frustum of a coneand connecting the central hub with the flame-spreader; an imperforatecylindric band inclosing the distributing pipes, and a bulgedcollarinclosing the cylindric band and having an upper and a lower lineof perforations, and spring-fingers secured to the bulged collar betweenthe said two series of perforations, as and for the purpose described.

4. In a gas-burner, the combination of a feed-pipe leading to agas-distribut-ing-chamber; upright distributing-pipes leading from thedistributingchamber to an annular cha1nannular chamber and resting onthe same,in-

side the line of jet-apertures; a flame-spread er resting on the topedge of the perforated cyl' inder; means connecting the flame spreaderand the central-hub for securing the perforated cylinder and theflame-spreader in po sition upon the annular chamber; a casing, A,having draft-holes, A, and supporting the burner; an impert'oratecylindrical band extending around the distributing pipes: abulged-collar inclosing the cylindrical band and having an upper and alower line of perforations; and spring fingers for retaining the chimneyof the burner in position, and secured to the bulged-collar between thetwo lines of perforations, substantially as described.

In testimony whereof I aifix my signature in the presence of twowitnesses.

SOLOMON M. KEMP.
